<string-array name="block"> <item>block a</item> <item>block b</item>  <item>block c</item>   </string-array>   <string-array name="level">   <item>ground floor</item>   <item>first floor</item>   <item>second floor</item>   <item>third floor</item>  </string-array>

the scenario:

1.if select block or b in blockspinner, content in levelspinner have ground,first , second floor.

2.if select block c in blockspinner, content in levelspinner have item in string array - level

public void onitemselected(adapterview<?> parent, view view, int pos, long id) {       spinner spinner = (spinner) parent;      if(spinner.getid() == r.id.spinner1) //do spinner1      {        //fill spinner2      } }
